X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=1bdba1a7141cb88e93bd10aa8af9bb94c6f98a09;p=emacs.git

Add configury for JIT

* configure.ac: Add --with-libjit.  Check for open_memstream.
* src/Makefile.in (LIBJIT, LIBJIT_CFLAGS): New variables.
(EMACS_CFLAGS): Use LIBJIT_CFLAGS.
(base_obj): Add jit.o.
(LIBES): Use LIBJIT.
